Referring to fig. 1 and 2, the application provides a trade roof beam equipment with lateral shifting function, including setting up travelling car 1 on trading the existing bridge in a roof beam piece both sides, trade the top of a roof beam piece and be equipped with a pair of steel box girder 2 that sets up along the bridge longitudinal direction, form the lintel hole that is used for the roof beam piece to pass between a pair of steel box girder 2, be equipped with horizontal transmission portion 3 between the bottom of steel box girder 2 and the corresponding travelling car 1, horizontal transmission portion 3 is used for driving steel box girder 2 and moves along the bridge transverse direction.
In the actual construction process, the movable trolley 1 moves to the existing bridge on two sides of the frame-changing beam piece, so that a frame-changing hole position is positively changed by a beam-passing hole formed between a pair of steel box beams 2, after the old beam piece is dismantled and connected, a beam feeding process needs to be carried out, and under the matching of a hoisting machine such as a gantry crane on the steel box beams 2 and the like and a beam-carrying trolley at the bottom end of the new beam piece, the hoisting machine can hoist the new beam piece and start to drop the beam, so that the erection of the new beam piece at the frame-changing hole position is completed.
In the processes of hoisting the old beam and dropping the new beam, an operator can determine the transverse displacement of the beam piece according to the actual working condition of the bridge and control the transverse displacement of the steel box girder 2 through the transverse transmission part 3, thereby finishing the transverse displacement of the beam piece. Therefore, in this scheme, the lateral transmission portion 3 is provided, whereby the lateral movement of the beam piece is realized.

Still include spacing portion 7, spacing portion 7 is used for spacing in order to avoid breaking away from between steel box girder 2 and the transverse transmission portion 3 to steel box girder 2.
Because the transverse movement of the steel box girder 2 is carried out under the state of bearing the girder piece, and the hoisting machinery is connected with the new girder piece through the rope, the situation that the steel box girder 2 is connected with the transverse transmission part 3 unstably or separated can occur due to inertia in the transverse movement process of the girder piece, and the girder piece can move slowly in the connection or feeding process, the problem that the gravity center of the steel box girder 2 shifts longitudinally is easily caused, and a certain possibility exists that one side of the steel box girder 2 tilts upwards, so that the situation that the connection between the steel box girder 2 and the transverse transmission part 3 is unstable or separated can occur. In order to avoid the phenomenon, a limiting part 7 is arranged, the steel box girder 2 is limited through the limiting part 7, and the limiting part 7 can adopt a conventional limiting structure, such as connecting the steel box girder 2 with the transverse transmission part 3 through a bolt connection mode and the like.
